A copy is prepared from an original sheet having imaged areas which are relatively infrared absorbing heat generating compared to the sheet, by assembling the original, a material supply sheet which carries a coating of material which is rendered plastic at a certain temperature and a copy sheet which has a surface adjacent the coating of transfer material, applying an evenly . distributed pressure to the assembly and imping- ing infra-red radiation thereon so that parts of the transfer coating corresponding to the image areas on the original are transferred to the copy sheet and remain there when the sheets are separated. The copy sheet may be the non-imaged surface of the original sheets and more than one copy sheet, original sheet and supply sheet may be used in the assembly. The sheets may be assembled in two basic ways (a) for the reflex technique in which the infra-red rays pass through the supply sheet to the original sheet and the heat generated passes in the opposite direction and (b) for the shoot-through technique in which the infra-red rays are directed straight on to the original and the heat passes in the same direction on to the supply sheet. Various assemblies are described for producing reversed and read-through copies on the copy sheet. The original sheet, the base of the supply sheet and the copy paper may be made of paper, cloth, plastic, glass, wood &c. provided they have the desired characteristics of smoothness, thickness and infra-red transparency: various numerical examples are given. The transfer material comprises a mixture of waxes, dyes and oils. The oils used are divided into two classes, "major" oils which are mineral oils and "minor" oils which are vegetable and animal oils.

Abstract: 1,001,393. Cable and wire terminals. AMP Inc. Oct. 14, 1963, No. 40368/63. Heading H2E. A method of making an electrical connection between a ferrule and a conductor, comprises introducing a mixture of ingredients which react to form a setting resin at the interface between the conductor and the ferrule, and before the resin sets, crimping the ferrule about the conductor so that the mixture flows over the interface and then is squeezed out of the crimp, the mixture then setting to seal the connection. The ferrule 2, has a ring tongue extension 4, and is surrounded by a metal sleeve 6, surrounded by an insulating sleeve 8. Separate capsules, e.g. 16, of suitable monomer and hardener are held against the surface of the sleeve 8, by a plastic covering 18. Adjacent to the capsules is hole 10. During crimping the capsules are ruptured and their contents flow into the interior of ferrule 2 and wet the surface of the wire and internal surface of the ferrule, excess mixture is squeezed out of the joint, but any interstices within the crimp are filled with resin, and a continuous seal is formed at each end of the ferrule. In a second embodiment, Fig. 5 (not shown), the ferrule is not surrounded by sleeves 6 and 8, but the inner surface of the ferrule has two internal annular grooves in which are mounted lengths of tubing containing the monomer and hardener.
